Orbital Tumor
Dody Priambada,
Objective
Orbital cavity is a small area with many structure lies there. The difficulty with the orbital anatomy stems from the highly compact three dimensional space that contains vital neurovascular structures suspended in sea of fat. Muscle, Lymphoid, Vessel, Duramater, Fibrous tissue and the important thing: optic bulb and optic nerve. Exophthalmus, pain, diplopia swelling, tearing, and blurred vision are common presenting symptoms. Although Exophthalmus is a cardinal sign, it is not limited to orbital tumor. The tumor origin could be from the structure it self, metastases, or continuing from intracranial.
Material and Methods
The study report 5 cases of orbital tumor between 2003-2006 in
During remove the tumor, close identification of intra orbital vital neurovascular structure must be done. The tumor is separated carefully and gentle to avoid destruction of the vital neurovascular structure
Result
Resection of tumor was done to remove the tumor. Beside remove the tumor the cosmetic problem ( exophthalmus ) is an important thing. Although exophltalmus decreases in all patients, it is not totally disappeared. The osteoma is the difficult one because the bone is very hard. The histopathologic results were: the man one has malignant tumor, an adenoid cystic carcinoma, it is from lacrimal gland ; the 3 women are benign meningioma and another woman is osteoma
Conclusion
Five Orbital tumors have been reported with different origin. One is malignant. The approach is depending on the location, combine is recommended if the tumor lies widely anterior and posterior of the bulb. Close identification and gentle tumor removal is needed to avoid destruction of the vital neurovascular structure
